ATM networks being a connection-oriented technology are providing service for real-time communication. Before two hosts can communicate, a connection has to be established between them. After a connection is established, messages are divided into fixed size packets called cells and are being sent from a source host to a destination host. Real-time communication service requires the underlying n...

We consider the effects of tuning d e l a y in optical broadcast networks. We show that for offl ine scheduling these effects are small even i f the tuning time is as large as the packet duration. In particular, we consider scheduling of random traffic with tunable transmitters and fixed-tuned receivers. We provide a lower bound to the completaon time of any off-line schedule with an arbitrary ...

The rapid development of online self-service applications has created the need for empirical studies about consumers’ perceptions and behaviour during the adoption and use of such systems. An essential condition for understanding the elements that can enhance the adoption and use of these online systems is to identify the main factors that define the quality of self-service applications from th...
